I learning orcad 9.2 capture then layout plus.....
anyway i was reading tutorial after drawing and saving the schematic the tut. say to go tools>netlist but i don't find the tools option so, netlist can be done for layout plus....
pls help me how to start i think this will be software
thanks

I am reading introduction to Orcad pcb layout tut.
according to tutorial while placing component the symbol for Pspice and layout should be shown in place window but in my window no symbol are appearing on any component, why??

Are those your own libraries or are you talking about the original ones, if there are some?
By layout symbol you mean footprint for pcb? It could be that you´re looking into a wrong library..

Also, when you place a schematic you can edit each part and assign the pcb footprint variable, using the name of footprints you find in c:\Cadence\SPB_16.5\share\pcb\pcb_lib\symbols\
at least that is the way it is done in 16.5

I have created the net list there are many option in window but i want layout only so, i have selected it then it ask for run ECO in layout what is this??
and showing many error how to move forward by removing error??

I'm starting to loose faith in humanity. Can't you realize that asking "It gives me some errors, how do I correct them" makes no sense?
How am I supposed to tell you what to do when I don't know what those errors are....

The first is things are just warnings that inform you on changes in the schematic after say moving a part. The second are kinda strange, because they say that pin 1 of D7 is connected to two different nets at the same time which I think should not be possible to achieve. You probably need to check the schematic to see what is going on. Can you post a screenshot?
